Abstract: To provide a laminated glass for a vehicle window which can prevent the temperature increase in a vehicle.
An infrared reflection glass plate which is a glass plate with an infrared reflection film, wherein the infrared reflection film has a stacked coating film (X) having a coating film (1) made of a high refractive index inorganic material having a refractive index of at least 1.90 and a coating film (2) made of a low refractive index inorganic material having a refractive index of at most 1.56 alternately stacked in this order from the glass plate side; the total number of the coating film (1) and the coating film (2) is at least 3; and the geometrical thickness of the coating film (1) is from 70 to 150 nm and the geometrical thickness of the coating film (2) is from 100 to 200 nm.
